So I searched for "IPCC consensus global warming" and came up with your article:

Fair enough. In the interest of disclosure:
Quote:
The 928 papers were divided into six categories: explicit endorsement of the consensus position, evaluation of impacts, mitigation proposals, methods, paleoclimate analysis, and rejection of the consensus position. Of all the papers, 75% fell into the first three categories, either explicitly or implicitly accepting the consensus view; 25% dealt with methods or paleoclimate, taking no position on current anthropogenic climate change. Remarkably, none of the papers disagreed with the consensus position.
Admittedly, authors evaluating impacts, developing methods, or studying paleoclimatic change might believe that current climate change is natural. However, none of these papers argued that point.
Joph linked the same article many moons ago as well. Of course, "75% of the papers" is not the same as "75% of climatologists agree". It just means that most of those who submitted papers to the ISA fell into that category.
Um... It also would help to read the footnote (#9 IIRC). Basically, if a paper wasn't "about climate change" it wasn't included as part of that section. Um... Makes one wonder what criteria they used to decide if a paper was "about climate change" and therefore included under that ISA category.
You also have to realize that depending on who's terms you're using, the phrase "climate change" can have different meanings, and this in turn can lead to some seriously misrepresentation of the "facts". This is one of the reasons why many of Joph's external articles are IMO not meaning what Joph thinks they mean.
The
FCCC (Framework Convention on Climate Change) defines climate change as:
"a change of climate that is attributed directly or indirectly to human activity, that alters the composition of the global atmosphere, and that is in addition to natural climate variability over comparable time periods." The
IPCC (Intergovernmental Panel on Climate Change) defines climate change as:
"any change in climate over time whether due to natural variability or as a result of human activity." How this can be misleading is that the IPCC does not actually do their own research. They use papers written by others to make political recommendations. I hope we can all see the problems that occur if the IPCC is using papers written about climate that use the FCCC's definition of climate change to support positions and recommendations that use their own. So, if they find 100% of the papers written about climate change conclude that it's occurring as a result of human activity, their use of the phrase "climate change" makes it appear as though this means that all the science says that the climate is changing as a result of human activity. But the source papers are *only* those that specifically talk about human impact on climate, so they've produced an incredibly misleading pseudo conclusion by only looking only at fact that support their own positions.
Similarly, when Joph cites papers and studies talking about climate change being caused by human activity, but none saying it's happening as a result of natural activity, it's equally irrelevant. Um... By definition all papers talking about "climate change" are only talking about changes due to human activity. It should not be surprising at all to not find any citing natural causes...
Yeah. Semantics. I know...
